• mixtures
  • For the first time, chemo-resistive gas sensors are exposed to dynamic gas mixtures generated with several concentration levels at the sources. (mdpi.com)
  • We used a support vector machine as a tool to show that chemo-resistive transduction can be utilized to reliably identify chemical components in dynamic turbulent mixtures, as long as sufficient gas concentration coverage is used. (mdpi.com)

  • Detection
  • Chemical detection systems based on chemo-resistive sensors usually include a gas chamber to control the sample air flow and to minimize turbulence. (mdpi.com)
  • comprehensive
  • While at Cornell, McLafferty assembled one of the first comprehensive data bases of mass spectra and pioneered artificial intelligence techniques to interpret GC/MS results. (wikipedia.org)
  • time
  • The aim of this work was to assess the suitability of matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) for routine heterotrophic monitoring in a drinking water treatment plant. (environmental-expert.com)
  • Science
  • The science payload mass is about 45 kg and consists of: The lander radio-science experiment (LaRa) will study the internal structure of Mars, and will make precise measurements of the rotation and orientation of the planet by monitoring two-way Doppler frequency shifts between the surface platform and Earth.

  • natural
  • However, such a kind of experimental setup does not reproduce the gas concentration fluctuations observed in natural environments and destroys the spatio-temporal information contained in gas plumes. (mdpi.com)
  • Sources
  • Aiming at reproducing more realistic environments, we utilize a wind tunnel with two independent gas sources that get naturally mixed along a turbulent flow. (mdpi.com)
